ok, i have a powerbook g4 12in and i was wondering what hard drive i need to get. im in okinawa right now so no mac stores. i dont know if i need to upgrade it or if i have to get the one that it comes with. either way can you let me know which one i have to buy so i can give this hp away i hate windows and i needed a comp so i bought this (regretfully). thanks for your help also is it hard or costly to recover all the memory off my old hard drive?
